Part 1 The Small Nadari

Dia 2 shows the same joseki where White has realised that his stone
in the upper left breaks the ladder and has played 10 instead of the the
hanging connection (at 16 - Ed). Black might as
well resign.

What else can Black play? Dia 3 shows a different position in which
Black has simply connected at 6. With Black's positions top right and
bottom left I feel that White has no particularly good way to play and
he will concede Black a lot of good secure territory while not making
himself much himself. Ishida recommends A as the next move but with
Black's influence already in place, White will not make much and Black
still has a move just below 5 to force White while increasing the size
of his corner. I hope that these simple thoughts make you pause for a
moment the next time you start to play a complicated joseki
automatically.

Finally, to cheer you up, I played the moves in Dia 4 in a recent
tournament game and played White 12 instead of the hanging connection,
and I hadn't even checked to see if the ladder worked. It's all to easy
to make mistakes in difficult joseki - and no one is immune.
